US Patent 10518944 Drinking vessel lid assembly

A lid assembly is provided comprising a lid main body and a lid valve subassembly removably attachable to the lid main body. The lid main body includes an upper portion having a drinking aperture and a first attachment element positioned below the upper portion in a lid cavity. The lid valve subassembly includes a subassembly main body, a sealing member, and an attachment collar rotatably attached to the subassembly main body. The attachment collar may be rotatable about an axis of rotation relative to the subassembly main body to selectively transition the lid assembly between an integrated configuration with the lid valve subassembly secured to the lid main body and a cleaning configuration with the lid valve subassembly separated from the lid main body. A second attachment element on the lid valve subassembly may engage with the first attachment element to releasable secure the lid assembly in the integrated configuration.
